CASH, CASH EQUIVALENTS AND INVESTMENTS |
3. | CASH, CASH EQUIVALENTS AND INVESTMENTS:
The Company’s portfolio of fixed income securities consists of term bank certificates of deposit, U.S. Government bonds and convertible notes. The Company considers all highly liquid debt instruments purchased with an original maturity (maturity at the purchase date) of three months or less to be cash equivalents. The Company classifies its remaining debt security investments as available-for-sale. These debt securities are carried at fair market value, with unrealized gains and losses reported in shareholders’ equity. Gains or losses on securities sold are based on the specific identification method. Cash and Cash Equivalents
